Public Address System

Product Details:

• Public address and voice alarm systems from Bosch With more than 90 years of experience in public address and voice alarm (PA/VA) solutions, Bosch Security Systems develops systems that deliver the highest performance in speech and music quality. Building on industry-leading technology, we work to continuously improve our systems. We focus on putting end-users first, by designing highly intuitive interfaces that make it easy to get the most from our products. Our goal is to address changing customer needs with outstanding systems that cater for applications of every size.
• Saving lives with public safety Securing people from potentially dangerous situations is our contribution to society. The voice alarm functionalities of Bosch PA/VA systems provide clear guidance and instructions in case of emergencies. Research proves that unlike traditional siren alerts, instructed evacuations reduce the time required to clear buildings, so more lives can be saved. Unique industry position As an industry leader, Bosch sets and maintains the highest standards of system availability and innovation. This allows us to meet and exceed the needs of our growing customer base, with guaranteed system reliability and built-in fail-safe redundancies. Our leading-edge technologies have integral compatibility, offering guaranteed interoperability and at the same time ensuring complete protection against eavesdropping and hacking.
• Ready for the future Bosch invests a large part of its turnover in global product and research development every year. Our PA/VA innovations have helped shape the development of the public address and voice alarm market. PRAESIDEO was the world’s first networked digital public address and voice alarm system. Today we continue our push for innovation, working hard to stay ahead of the trends identified as part of our ongoing research. Market insights show that customers need solutions that can quickly accommodate changes to building use, instantly incorporating newly defined areas or changes in areas. Customers prefer solutions that can use existing infrastructure and support remote diagnostics and maintenance, leading to cost efficiencies. And because the current need for integration of all building management systems, there is a clear trend towards
• IP-based systems and softwarecontrolled devices, resulting in more future-proof solutions. The launch of our most recent public address and voice alarm system answers these trends, and more. Fully IP-based PRAESENSA integrates the power of OMNEO media networking architecture. Based on open standards for high interoperability, OMNEO distributes high-quality audio and control data over standard IP networks.
